Here’s an easy mayo mustard sauce with a bit of kick. Spread it on burgers, sandwiches, or sausages, or use it as a dip. With just two ingredients, it’s quick to make, and it’s ready in under 5 minutes!

This mayo mustard sauce is my go-to when I want big flavor with almost no effort. It’s made with just two ingredients, which almost feels too simple to call a recipe, but it’s so useful that I make it all the time.
I originally started making it for my German-inspired bratwurst burgers , but it quickly became a staple. I use it on burgers, sandwiches, and sausages, and it doubles as an easy dip for fish cakes, fries, chicken strips, or fresh vegetables.
One of the things I love most is how easy it is to customize. Different mustards give it a completely different personality, so I’ll mix it up depending on what I’m serving. It comes together in seconds, keeps well in the fridge, and is perfect to have on hand when I need a quick flavor boost. For something extra special, try making this dip with my easy mayo recipe !
